ELECTRICAL INSTALLATION
ELECTRICAL SHOCK
Remove power from FF-SR Series control modules and
machine during installation.
Failure to comply with these instructions could result
in death or serious injury.
Multiple wiring configurations are possible for the
FF-SRS5934 single channel emergency stop module.
General guidelines are provided because there are
various ways to interface the module to machine control
circuitry. Refer to the important warnings (page 5) and
the application examples (page 6).
FUNCTIONAL DESCRIPTION
In an automatic start configuration, the module accepts
immediate input from the safety device (emergency stop
push button or safety switch) between L1/A1 (see
application example). If S33/S34 and Y1/Y2 are jumpered
(or closed), the normally open safety contacts (13/14 and
23/24) will close.
In a manual start configuration (start push button is
between S33/S34), the module accepts input from the
safety device (emergency stop push button or safety
switch) between L1/A1 after activation of the start push
button (see application example). If Y1/Y2 are jumpered
(or closed) when the start push button closes, the
normally open safety contacts (13/14 and 23/24) will
close.

In either configuration, if the safety device is actuated
(emergency stop condition occurs), the normally open
contacts will open immediately. This emergency stop
condition is relayed via the safety contacts of the module
to the machine control circuitry to arrest dangerous
motion and/or remove power.
One or more FF-SRE3081 Extension Modules or external
contactors with positively driven contacts can be used to
multiply the number of contacts of the FF-SRS5934
Emergency Stop Module. If multiple safety contacts are
used in parallel with one load, the maximum admissible
current can be increased.
LED INDICATORS
The FF-SRS5934 module has two green LED status
indicators (Power, K1/K2) as illustrated below.
The Power LED indicates power is applied to the safety
control module. Illuminated K1/K2 LED indicates that both
internal safety relays are energized. Both K1 and K2
relays must be energized to have the normally open
contacts 13/14 and 23/24 in a closed condition.
